If we're convinced it's worth it, seems like the right way to do it= ,
and certainly cltv and rclv/op_maturity are related.
But let's not forget that we can always use this same trick with the last opcode to get 2^64 brand new opcodes.
So I'm not convinced at all on whether we want=C2=A0 #5496 or #6124. But it would be nice to decide and stop blocking=C2=A0 this.
